Hey man
Your plants are looking good.
This is what to expect when growing autos, it will start to show sex soon if it has not already and it will be slowly moving into flowering phase.
I see a few Pistils in your DG plant, so that's a good sign I would still wait a week or so before switching to flower nutrients until more pistils and some mini bud sites are showing. Just like
@gmslave said below, don't fully cut out the grow nutrients are still need just in much smaller amounts.
They will all start to feed a bit more giving they are maturing into adult plants now.
Auto's feed a bit less then the typical photoperiod strain and so bottle directed amounts can be to much sometimes.
This is a good reference point for ec/ppm numbers for auto feedings.

Best of Luck and Happy Growing!
